The cellular network business is one of the most competitive in the world, but it's also one of the most lucrative, and it's only growing. That being the case, it's not surprising that American telecom giant Comcast may be looking into entering this hotly-contested market. According to a report on The Information, Comcast is hoping to use its huge userbase of home Internet customers to create a combination Wi-Fi and cellular network, competing directly with carriers like AT&T, Verizon, Sprint, and T-Mobile.

If there is one thing we all eventually rely on with mobile devices, it's having a sturdy Wi-Fi connection. Whether it's because of a low data cap, you live or work somewhere with a weak cell signal, or like me, the local cellular technology is stuck in the stone age, you probably have a few wireless networks saved on your phone or tablet. While you probably take it for granted that your devices will automatically connect to these networks when they are in range, some people are finding that feature hasn't been working as expected since upgrading to Android 4.3.

Surfing the web while on the move has become a reality thanks to mobile internet over 3G or LTE. However despite yearly advancements in its technology, the reliability of mobile networks remains lackluster.

A solution to ubiquitous connectivity has come in the form of blanketing various cities with wireless hotspots. For example, in Singapore the Infocomm Development Authority (IDA) have initiated the [email protected] program which aims to provide wireless hotspots all across the island.

Although it wasn't announced alongside the plethora of other features during the Ice Cream Sandwich event, Wi-Fi Direct may prove to be one of the more important and revolutionary features of the new OS. In the old days Bluetooth was the standard method of device to device data transfer, but now with Ice Cream Sandwich we are given Wi-Fi Direct and Android Beam. The latter uses NFC to transfer links, media, and other data, while the former is an interesting implementation of the wireless standard which creates ad-hoc networks between compatible devices.
